4100 Guided Wave Radar Level Transmitter
About 4100 Guided Wave Radar Level Transmitter
HollySys 4100 Guided Wave Radar Level Transmitter guides the microwave pulse downwards onto the measured medium through a waveguide rod, and some signals are re flected back. The level is determined by measuring the time difference between signal transmission and reception.
Product Features
-
Reliability"ELL signal analysis technology" can reduce the impact of various false echoes to ensure high reliability of products.
-
